An image scanner capable of precisely inputting information is disclosed. A light transmission path is formed through a wall portion of a scanner body to enable the operator to visually confirm a reading position on the document from the outside of the scanner body through an opening for reading the document. A read starting position on the document can be confirmed by turning on the light source only without inputting the information to a data processing means according to a signal from a scanner body moving amount detecting means.
